Biting the leash
My pup has begun playfully biting at and holding onto the leash when we are on a walk. He only does it when he is really excited, like when we first leave the house, normally he walks just fine. What should I do when he does this?
If I just stop and remain motionless, I still have to hold onto the leash, which turns into a game of tug for him, even if I turn around and ignore him or sit down. I have stood still for at least 10 minute before on the sidewalk, waiting for him to release the leash so we could continue, but to no avail. The only reason we completed our walk was because he saw a squirrel elsewhere and became focused on that, releasing his grip in the process.
If I bring out treats and do obedience drills with him, he goes through the drills beautifully but when we finish and I start walking, he starts biting the leash again. Obviously I can't just let go of the leash on the sidewalk.
He also grabs onto clothing - skirts, jeans, jackets, and does the same thing when we're walking and he is too wound up. He just doesn't seem to get the idea that biting leash/clothing = stop walking.
